Locate the required file in a changelist and do one of the following:
Right-click the file and select
.Select the file and press Ctrl+D.

Compare local changes with the base revision
Apart from navigating through your local changes within a file in the editor, you can review these changes compared to the base revision of the file.
To preview the diff, select a modified file in the Commit tool window and click on the toolbar.
The left pane shows the affected code as it was in the base revision, and the right page shows the affected code after you've made changes locally.
Use the toolbar buttons and controls to navigate between changes and configure the appearance of the Change Details pane or the Diff Viewer:
Item | Tooltip and Shortcut | Description |
---|---|---|
/ | Previous Difference / Next Difference Shift+F7 F7 | Jump to the next or previous difference. When the last or the first difference is reached, DataSpell suggests clicking the arrow buttons or pressing F7/Shift+F7 once more and comparing other files modified locally. This behavior depends on the Go to the next file after reaching last change option in the Diff Viewer settings. |
Jump to Source F4 | Open the selected file in the editor. The caret is placed in the same position as in the Diff Viewer. | |
Compare Previous/Next File Alt+LeftAlt+Right | Compare the local copy of the previous or next file with its update from the server. | |
Go To Changed File Ctrl+N | Display all changed files in the current change set and navigate to them. This action is only available when you review changes to multiple files. | |
Viewers | Select a viewer mode: side-by-side or unified. The side-by-side mode has two panels, and the unified mode has one panel. You can edit code and perform the Accept, Append, Revert actions in both viewers. You can change text only in the right-hand part of the side-by-side viewer or in the lower line in the unified viewer. You can edit only local versions of your files. You cannot edit files that have read-only status. | |
Whitespace | Define how the Diff Viewer should treat whitespaces.
| |
Highlighting mode | Select the way differences granularity is highlighted. The available options are:
| |

Help F1 | Open a browser and show the corresponding help page. | |
Annotate with GitBlame | This option is only available from the context menu of the gutter. Use this option to explore who introduced which changes to the repository version of the file and when. The annotations view lets you see detailed information for each line of code, such as the version from which this line originated, the ID of the user who committed this line, and the commit date. For more information about annotations, refer to Locate code author (Annotate with Git Blame). |
